The Crown of Thorns at Notre Dame Cathedral in Paris. The relics of the Passion presented at Notre-Dame de Paris include a piece of the Cross along with the Holy Crown of Thorns, and of all the relics at the Notre Dame de Paris Cathedral, the Crown of Thorns is without a doubt the most precious and the most revered.
While the Crown of Thorns is not exhibited at the Concierge this autumn (it returned briefly to the Sainte Chapelle for a religious celebration in March 2014), the shirt, scourge and hair-shirt has been lent to the exhibition and takes pride of place after a parade of romanticising paintings from the 19th century.
